Hi, I built it today : it's obviously an easy build, and works as expected :) It might not be a top of the line fuzz, but it does the job. Is there an easy way to get more output from it?
Was attempting this today, I had no 33nf caps so I used a 47nf and it's not working at all. Would this be the reason? I can't find any other reasons, I've checked all the components and checked for continuity. The only issue I can see is that row 4 is going to ground. I'm not super great at reading schematics, I'm learning but still don't fully understand. Should row 4 be going to ground of is this something I need to rectify?
This is now my new favourite one knob Fuzz, its amazing. Splutters so nicely. Had some time to kill today so knocked this one out in about 10 mins. Well worth making! I changed some values as I didnt have to parts: 120nf greenie instead of 100nf. 22nf instead of 33nf. And after testing 7-8 different transistors I settled on a PN3565. Haven't boxed it up yet but sounds amazing.
Finally got mine working, the main issue was the a100k pot I was using was busted. Then when I put it in the enclosure it stopped working again. The wire from amount 2 to the output broke underneath the silicon sleeve whilst putting it in the pot. Also the footswitch pcb and the enclosure I used had the LED on different sides so I had to desolder it and then extended it using wires, which ended giving me the smallest of bridges. But after much hair pulling and swearing it eventually came to life and it sounds awesome! I had to make a few adjustments and ended up using BC549c trannys as it was the closest hfe and I didn't have a 33nf so had to use a 47nf (although I might change it for a lower value in the future because I'm guessing that's the thick switch to give it more bottom end?)
Anyways sounds great, lots of spluttery goodness that goes from stoner/doomy sounds down to pulp - disco 2000!

ReplyDeleteSorry, just realised its because that switch isn't activated its going to ground.

Hey hey, any chance of getting a layout for the walrus 385? Such a great overdrive but can't find any schematic for it.
